If I'm not mistaken, I believe I saw ketchup on the food pyramid in elementary school in the 1980's. :(
That's why the cheeseburger is a perfectly balanced food pyramid meal. You have protein from beef, dairy from cheeze product TM(contains no actual cheese), grain from the bun, AND your fruit and vegetables from the ketchup.
